SAGINAW, MI — Beginning in April, crews will begin work reconstructing a 4-mile stretch of northbound Interstate 75 and replacing bearing pads on the Zilwaukee Bridge in Saginaw County.

In Bay County, I-75 from Pinconning Road to the Bay/Arenac county line is set for a concrete overlay starting in April as well.

The two projects are among several in Bay, Saginaw and Midland counties planned by the Michigan Department of Transportation for 2014.

The I-75 Zilwaukee Bridge project began in October 2012 and is expected to be completed in April 2015.

The two-year, $61 million project includes concrete reconstruction with bridge replacement on Janes Road, bridge rehabilitation on Wadsworth Road and over CSX Railroad, and bearing replacement on the Zilwaukee Bridge.

During the 2013 construction season, crews reconstructed four miles of southbound I-75 and replaced bearing pads on the southbound lanes of the Zilwaukee Bridge, according to the Michigan Department of Transportation. The same work across northbound lanes begins in April.

It is one of nine Michigan Department of Transportation projects to take place in Saginaw and Bay counties this year, and one of three in Saginaw and Bay counties considered by the department to be “high impact.”

“Generally, high impact projects are going to be on corridors of significance, like I-75, I-69, U.S. 23 (and U.S. 10 and U.S. 127),” said Anita Richardson, Michigan Department of Transportation spokeswoman. “These are highways with the most significant traffic volumes and they also tend to be the highways that are most conducive to trade.”

MDOT officials say the I-75/Zilwaukee Bridge project will affect traffic in the following ways:

  • Sunday through Wednesday,

    northbound traffic will be detoured to I-675 (two lanes). Southbound traffic will be routed to northbound I-75 (three lanes).

  • Thursday through Saturday, northbound traffic will remain on northbound I-75 (three lanes). Southbound traffic will be detoured to I-675 (two lanes).

    In Bay County, the I-75 project is expected to wrap up in November at a cost of $4.99 million.

    Also in Bay County, interchange reconstruction, bridge replacement on M-47, bridge rehabilitation on Hoppler Creek, Huron and Eastern Railroad and westbound US-10 over Patrick Road is slated to begin in June.

    The $5.49 million project is expected to conclude in November.

    Several lower-impact projects are planned for both Saginaw and Bay counties this year.

    “MDOT provides both printed and online versions of this map so that as many motorists as possible are prepared for Michigan's upcoming construction season,” State Transportation Director Kirk T. Steudle said in a prepared statement. “We remind everyone to slow down and be alert when driving through any work zone.”

    “Nearly 99 percent of all people hurt or killed in work zones are drivers and their passengers. Avoid distractions, don't tailgate and pay attention to barrels, cones, signs and workers.”
